STARTING-CRANK FOR AUTOMOBILE-ENGINES.

Original application filed April 23, 1917,

To all whom it may concern:

Be it known that I', VINCENT G APPLE, a citizen of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented certainnew and useful Improvements in Starting-Cranks for Automobile-Engines, of which the followingis a specification.

My invention relates to improvements in manually operable and separable crank starters for automobile engines.

One of the objects of my invention is to provide a hand operable crank starter for emergency use for starting the engine of an automobile when the automatic starter fails to work.

' Another object is to provide a crank starter having an axially movable head for insertion in the orifice of the end plate of a dynamo when the current regulator has been removed for the purpose.

Other and further objects of the invention will become readily apparent, to persons skilled in the art from a consideration of the following description when-taken in conjunction with the drawings, wherein Figure 1 is a central section of an end plate of a dynamo electric machine having an axial orifice within which to normally contain a current regulator, showing the head of the crank arm applied thereto.

Fig. 2 is an end view of a portion of the dynamo showing the end plate and the end of the shaft through the regulator orifice.

In all of the views the same reference characters are used to indicate similar parts.

This application is a division from my original application Serial No. 163,803, filed April 23, 1917.

In the original application, a dynamo electric machine for starting the engine and for charging a battery and a current regulator removably insertible in an axially disposed perforate end plate of the dynamo is disclosed. In the present application, sufiicient of the end plate is shown to define the axially disposed orifice and the end of the shaft upon which the armature of the dynamo is mounted.

In the original application the armature is directly mounted on the prolonged front end of the engine shaft and a current regulator, of novel design and arrangement of parts, is detachably secured in the orifice provided for it in the end plate, so that Specification of Letters Patent.

the axis of the regulator is in axial alinement with the axis of the dynamo, and an axially movable contact member carried by the regulator, cooperates with, a rotatable contact member carried by the engine shaft. The regulator is self contained or its parts are organized in a separable unit so that it may be easily and quickly removed to permit insertion of the starting crank.

In the drawings 5 is a part of the armature' of the dynamo electric machine. 6 is 1 the end of the shaft upon which the armature is mounted. 7 is the eccentrically disposed contact in the shaft which cooperates with the contact of the regulator, not shown. 8 is the spider of the armature and 9 is the threaded nut for holding the spider in place, having radially projecting arms 10 and 11 for engagement by the head 12 of the crank arm 13. The plate 14 that extends across the axis of the armature and which is fixed to the magnet frame of the dynamo in a suitable manner, is preferably made of insulating material, such as bakelite or the like and is provided with an axially disposed orifice 15. In this orifice the regulator is to be normally contained. The cup-shaped member 16 fills the orifice and serves as a guide for the head 12 and for the crank arm 13. The cup is reduced in diameter, as at 17, to more snugly fit the body part of the crank arm.

The head is provided with ratchet shaped notches 18, four in number, two of which, that are oppositely disposed, engage the arms 10 and 11 of the nut 9 to rotate the shaft 6 when the crank is turned.

An open helical spring 19 is wound about the crank and secured thereto, as at 20, and tends yieldingly to move the ratchet teeth ,of the head 12 out of engagement with the I arms 10 and 11, so that when the crank is applied it must be pushed inwardly against the resistance of the spring 19 to engage the arms 10 and 11 and when sufiicient revolutions of the crank are made, the spring 19 pushes the head outwardly in the cup- 16. from operative engagement with the shaft so that should the engine kick back, the crank will not be rotated by the reverse rotation of the shaft, due to the kick.

-Having described my invention, What I claim is 1. In combination with a dynamo having an end plate provided with an orifice having its axis in alinement With that of the armature shaft, of astarting crank having a cup on its end to substantially fill the orifice and a head Within the cup to engage the shaft, both removable With the crank.

- 2. In combination With a dynamo having an end plate provided With an orifice having its aXis in alinement with the armature shaft, of a starting crank having a loosely mounted cup on its end to substantially fill the orifice; a head Within the cup to engage the shaft and a spring Wound about the crank and bearing against the cup tending to yieldingly move the head from engagement With said shaft, said head and cup being inseparably attached to said crank,

3. A. starting crank comprising a crank arm; a hollow cup slidable on said arm and inseparably attached thereto; a head in said cup provided With parts. to engage ashaft, to rotate it, and an open helical spring Wound about said arm and bearing against said cup to push the latter over the head.

In testimony whereof I hereunto set my hand.
